This thesis summarizes the milestones achieved in building a thermoelectric generator (TEG) device using a novel p- and n- type 2-D thermoelectric material called Ge/SiGe superlattice; which was grown by low energy plasma- enhanced chemical vapour deposition (LEPECVD). It begins by describing in a nutshell the advance…
In modern pressurized water reactors (PWR), the substitution of nickel-base Alloy 600 and its associated filler metals Alloy 82 and 182 by Alloys 690, 52 and 152 with higher chromium content has improved the integrity of the main components in the primary circuit. However, metallurgical changes during thermal ageing o…
Three-dimensional topological insulators are fascinating materials with insulating bulk yet metallic surfaces that host highly mobile charge carriers with a spin orientation locked to the propagation direction. Such spin- velocity coupling facilitates the exciting possibility to launch spin- polarized charge currents…
Jüngste experimentelle Fortschritte erlauben die Beobachtung von elektronischen Relaxationsprozessen in Festkörpern in Echtzeit. Nach der optischen Anregung eines Systems relaxiert dieses in einen Gleichgewichtszustand. Die Dynamik des Systems während des Relaxationsprozesses ist von den vorherrschenden mikroskopische…
The behaviour of two graphene based structures has been theoretically investigated and analysed by using one or more tools. This tool kit consists firstly of SIESTA, a density functional theory software package, secondly Gollum, a non-equilibrium Green’s function code, and finally the tight binding approach. The first…

The present research deals with the development of silk fibroin (SF) and chitosan (CS) based microporous 3D scaffolds for cartilage tissue engineering applications. Porous scaffolds prepared from SF/CS blends with varying ratio of SF and CS by freeze drying method were characterized for physicochemical, mechanical and…

Die vorliegende Arbeit beschäftigt sich mit zwei verschiedenen Schwerpunkten. Einerseits wurde im Rahmen der vorliegenden Arbeit das Auftreten höherer nichtlinearer Beiträge mittels mechanischer Spektroskopie für Polymethylmethacrylat (PMMA) untersucht. Dafür wurde in Anlehnung an dielektrische Messungen bei großen Fe…

Nuclear Magnetic Resonance (NMR) spectroscopy allows one to study and analyze the structure, motions and interactions of a broad variety of molecules. However, this technique has a major inconvenience: its low sensitivity, which therefore often results in the use of highly concentrated samples in order to observe tiny…
Modelling of hydrogen assisted stress corrosion cracking (HASCC) within the framework of mechanics is very important for its control and avoidance. The main focus of this study is to develop suitable approach for modelling and analysis of stable crack growth through high strength steels under HASCC. A new strategy bas…
Often a surface sensitive analytical technique in combination with sample erosion by inert ion sputtering is used for compositional in-depth analysis of solid state samples. Layer by layer the sample gets eroded and then the composition of the actual surface is estimated. The elemental detection limits can be increase…
The main goal of this work was the study of the applicability of a polymer film heat exchanger concept for the applications in the chemical industry, such as the condensation of organic solvents. The polymer film heat exchanger investigated is a plate heat exchanger with very thin (0.025 – 0.1 mm) plates or films, whi…
Within the scope of this thesis, a test stand Photo-CATCH for research on semiconductor photocathodes used at the spin-polarized electron injector of the superconducting Darmstadt electron linear accelerator S-DALINAC is constructed and brought into operation. Ultra-high vacuum conditions are achieved in all parts of…
Laminated bamboo could be a promising material when it comes to large span roofing structures where often truss structures are adopted. It is assumed that connection design used for timber trusses can also be applied in laminated bamboo trusses. For this research truss nodes with slotted-in steel plates are considered…
Self-healing materials have attracted significant attention from researchers during last decades. However, self-healing materials cannot find practical applications yet due to a weak mechanical strength. Recently, it was identified that an acrylic elastomer, VHB 4910, has an excellent self-healing ability accompanied…
Arrays of identical and individually addressable qubits lay the foundation for the creation of scalable quantum hardware such as quantum processors and repeaters. Silicon vacancy centers in diamond (SiV–) offer excellent physical properties such as low inhomogeneous broadening, fast photon emission, and a large Debye-…
